| passport | Used for user authentication, such as login. |
| jsonwebtoken | Token-based authentication for authenticating and identifying users. |
| axios | It is an HTTP asynchronous communication library that utilizes the Promise API, which is an API for flexibly handling asynchronous processing for browsers and Node.js. |
| CORS | It is an abbreviation for Cross Origin Resource Sharing. It is a package that blocks the API for security reasons by the browser when the client requests it to a server with a different domain and port. |
| express-rate-limit | A package that allows you to limit the number of incoming requests from one IP address per unit time. |
| UUID | Abbreviation for Universally Unique IDentifier, which is used by the server to distinguish users by attaching UUIDs. |
| ms | You can easily convert various time formats to milliseconds. |
| WS | The client and server can send and receive data to each other without disconnecting and maintaining the connection. |
| socket.io | It is a websocket implementation like ws, but it is a better choice when considering cross-browser compatibility or backward compatibility. |
| EventSource | A package that makes a persistent connection to an http server. |
| node-schedule | You can schedule it and run it. |
| sse | It is an abbreviation for Server Sent Events, and is a package that streams data from the server in real time. |
